When the fish takes spent spinners, do so with calm and controlled vigilance. These dead dragonflies will not disappear and are an easy prey. This is perhaps precisely why many fly fishermen often find fishing difficult when large numbers of dragonflies have died and ended up on the water surface at the same time. The abundant supply of dragonflies means that the fish do not even look at flies that do not fully imitate the spent spinners that lie there. When fishing with spent spinners, patience and perfect flies are required. The fish often take in these dead dragonflies calmly. So have ice in your stomach, wait out the countercut a bit.
